Although today hydrogen is distributed mainly by trailers, in the long terms pipeline distribution will be more suitable if large amounts of hydrogen are produced on industrial scale. Therefore from the safety point of view it is essential to compare hydrogen pipelines to natural gas pipelines, which arewell established today. Within the paper we compare safety implications in accidental situations. We do not look into technological aspects such as compressors or seals.
Using a CFD (Computational Fluid Dynamics) tool, it is possible to investigate the effects of differentproperties (density, diffusivity, viscosity and flammability limits) of hydrogen and methane on thedispersion process. In addition CFD tools allow studying the influence of different release scenarios, view more
